What is the significance of colostrum for a newborn?

Colostrum is the first form of milk produced by the mammary glands during the initial days after childbirth. Its significance for a newborn lies primarily in its rich composition of essential nutrients and antibodies, which is why the selected answer is accurate.

Colostrum is notably high in immunoglobulins, particularly IgA, which plays a crucial role in providing the newborn with passive immunity. This is important as newborns are born with immature immune systems and are susceptible to infections. The antibodies found in colostrum help protect the baby against pathogens they may encounter in their new environment.

In addition to antibodies, colostrum contains a variety of other beneficial components, including proteins, vitamins, and minerals that are vital for the newborn's development. The nutrient profile of colostrum is specifically tailored to meet the needs of an infant in the first few days of life, making it a critical factor in their health and well-being.
